HyperFrames: write a web page, render it as an MP4, and let coding agents do the writing

HeyGen's Apache-2.0 framework renders HTML, CSS, media and seekable animations to MP4. It comes with a CLI, a library of about 450 components, and skills that teach coding agents how to produce a video from start to finish.

HyperFrames is an open-source TypeScript framework, published under HeyGen's GitHub organization. It turns HTML, CSS, media and seekable animations into MP4 videos, and the project describes the output as deterministic. You can use it from a command-line tool, from coding agents such as Claude Code, Codex and Cursor through installable skills, or as the rendering engine behind hosted tools. It ships nine skills and about 450 ready-made blocks. It is Apache-2.0 licensed and needs Node.js 22+ and FFmpeg. Some features depend on HeyGen's Pro plan, and the README excerpt publishes no performance or fidelity figures.
